TYPE-WRITING MACHINE.

application filed J une18, 1914. Serial R 0. 845,888

To all whom it may concern:

Be it known that I, MARSHALL B. SAR- GENT, of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Type-W'riting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in typewriting machines and more particularly to paper feeding devices; especially to such as are adapted for use for moving the paper'strip in a stenographic writing machine,-th e object of my present invention being to provide the fingers of the feeding mechanism with separable pawls which may be easily inserted or removed or adjusted.

A. further object is to provide removable feeding pawls which may be sharpened at both ends, so that when one end of a pawl becomes dulled, it may be inverted to bring the other end in operative position.

With these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claim.

In the accompanying drawings, Figure 1;

is a sectional view showing a portion of a typewriting machine andillustrating an embodiment of my improvements, and Fig. 2 is an enlarged sectional view showing one of the feeding fingers.

1 represents a portion of the frame of a I stenographic typewriting machine, wherein a plurality of key-levers such as indicated at 2 are pivotally supported and provided with upwardly projecting arms 3.

Type-levers 4: are pivotally mounted between their ends and pivotally connected at their lower ends with the upwardly pro jecting arms 3 of the key-levers, the upper ends of said type-levers being provided with type 5 to engage a paper strip 6 passing in front of a platen 7 carried by a platen frame 8.

The platen frame is provided with rollers 9 over which the paper passes and with rearwardly projecting arms 10 pivotally con I nected at theirv rear ends to a mounted on the frame 1. v

A rock-shaft, 12 is mounted in the yoke 11 and provided at its ends with rigid arms yoke 11,

slightly inclined and- Patented Augi'3, 1915.

such as indicated at 13 each having a spring actuated feeding finger 14 mounted at its, upper end, the biting lower pof'tio'ii' of whifi normally rests (when nopaper is in the a machine) upon the slightly curved upper surface 15 of enlargements 16 formgd or parts to normal, positions after having fed movement of the paper strip will be pre-- vented by the action of a spring-actuated] finger '18 havingits biting lowr end disposed over a lug 19,said finger being cooperating with the upper surface of said lug in-a manner to gripthe paper. The finger 18 islmounted in arms, such as indicated at 20, projecting forwardly from the cross bar 21 of the yoke 11 and the lug 19 projects forwardly from a plate 22 fixed to the yoke 11 and spaced from the cross-bar 21.v

Each spring-actuated finger 14-18 is made in its lower to receive a remova 1e pawl 23 which forms the biting end of the finger, each pawl being beveled at each end to form bitin edges 24 and each pawl is held removably in place lugs 16 are moved or fed as these parts move backwardly. When the shaft 12 rocks fdr wardly to return the the paper, retrograde,

ortion with a socket 22 bymeans of a .set screw 25. A handle or i finger piece 26 projects upwardly from each gets as above described, the biting ends of the fingers may be easily adjusted, andremoved when worn and inverted or replaced by.new pawls, and furthermore, the necessity of making the entire finger of tool steel,

may be obviated, thus simplifying and cheapening the cost of manufacture,

For the purpose of oscillating the rockshaft 12 to efiect, the feeding of the paper when the key-levers are operated, an arm 27 depending from said rock-shaft is connected by a coiled spring pitman 28 with a rocking fram'e29 actuated by thekeydevers.

Having fully described'my invention what m I claim as new iiiaci desire to secin'e by Letten-Pat ent, is

Paper ieeliing mechanism comprising an @sciHawi'ynwmber, a member having a grip- 10 'ping face, and a handle portion projecting upwardly from said body portion of the v I In testimony whereof, l'have slgned this specification in the presence of two subscribing Witnesses.
